You are a life-saver! I kept getting the following error after converting my web project into a web application:
"Generation of designer file failed: Exception has been thrown by the target of an invocation."
Once I could see the log file, it pointed me in the right direction for solving the problem. In my case, the issue was a null reference on a private string in a class library. The string wasn't ever called at runtime so the compiler never complained about it. Apparently, the designer generation process will test some unused variables.
Thanks again!
No problem, its nice to see that a simple blog post did the job (i earned my nickel)
Any idea what the reg key is for VS08?
Didn't check , but I guess simply change 8.0 to 9.0, tell me if that works.
Also i heard people saying to reset the visual studio setting also helps (as a last resort)
Yep - changing 8 to 9 did it.
Unfortunately this didn't work for VS2010. Any idea?
Can you share what registry did you change and what other hives of registry you have ?
